Hello,
As a team we are developing embedded application in Qt/QML 5.15.18 for HMI display. We are also releasing this application as a WASM build for internal team as a customization version.
The problem is that when we run/open WASM version in browser we get sometimes this error
It actually occurs only when application is starting, we never get this error in runtime when app started without issues. Reproduction is around 1%-2% so it is hard to investigate. My biggest problem is that I don't know how to analyze this exactly. I don't know if his is error from the C++/emscripten/javascript code or any other area. And what tools to use to debug this memory issue in browser. -
